So I was digging a hole into a stone mountain. As I was digging stone I started hearing grass and dirt block being dug along with the stone I was digging (I was not playing multiplayer, wifi was off and I am playing on a Kindle Fire) I stop digging and wait. The sound stops. I quit the world and come back later. I continue digging and the grass sound comes back. This time when I stop digging I hear stone blocks being broken when I am not doing anything. The sound is repeating itself and getting slowly louder. I am wondering if this is a bug and if anyone else has heard this or knows what is going on. (I have an idea of what is happening and if you read this and know what you think I am hearing...yeah) Seed I was using:nyan
